8 Claims.

This invention relates to conductor supports and more particularly to `supports for comparatively light electrical transmission lines, and has for one of its objects the provision of a support which may be used for conductors of various sizes and which will be of fairly simple and cheap construction, easy to install and efficient in operation.

Other objects and advantages will appear from .the following description.

I The invention is exemplified by the combination and arrangement of parts shown in the accompanying drawing and described in the following specication, and it is more particularly pointed out in the appended claims.

In the drawing:

, Fig. l `is a top plan View of one embodiment of the present invention.

Fig. 2 is an elevation of the conductor support or clamp shown in Fig. 1.

' Fig. 3 is a section on line 3 3 of Fig. 2.

' In the embodiment of the Vinvention shown in the drawing, a body or seat member I0 is provided with a channel shaped seat II for receiving the conductor. The seat member Il) is curved downwardly at its ends to avoid an abrupt shoulder at the point where the conductor leaves the seat. A reinforcing rib I2 vextends longitudinally of the seat member to provide ample strength without undue weight. Projecting laterally at each side of the seat member is a wing or iiange I3, the flanges being perforated to receive a supporting U-bolt I4.

Disposed above the seat member is a keeper piece I5, one side oiwhich is provided with a bearing face IG having a longitudinal groove therein, the bearing face being curved in the direction of the length of the cable to conform approximately to the curvature of the seat in the body member I 0. The keeper piece I5 is provided with laterally extending ears Il which are also perforated to receive the U-bolt I4. At the opposite side of the keeper piece I5 from the seat I6 is asecond seat I8 having a longitudinally ex- U tending groove formed upon a shorter radius of curvature than the grooved seat I6. The seat I8 is curved in a direction longitudinal of the cable in a reverse direction` from the curvature of the seat I6 so that when the keeper piece is cable, the longitudinal curvature will conform turned over to bring the seat I8 adjacent the piece is reversed from the position shown in Fig. 3, the seat I8 will be closer to the seat I I than the position' of thev seat I6 shownin the drawing. It will be readily apparent that the keeper piece in the position shown in the drawing will accommodate conductors of diameters ranging from that indicated by the smaller ofthe two broken line circles in Fig. 3 to that 'indicated by the larger oi the two circles. 'For cables of smaller diamleter than that shown by the smaller lof the two broken line circles, the keeper piece is reversed and the seat I8 vis used for engaging vconductors of smaller size.

It will be noted from Fig. 3 of the rdrawing that when the cable isclamped in the support, the. flat faces of the lower nuts I9 engage the lateral faces of thefseat member Ii), thus locking the nuts I9 against rotation while the upper nuts '20 have sulicient clearance for the outermost portions of the nuts to pass the keeper piece I5. This .is true of the upper nuts for both positions of the keeper piece I5.

In installing the device, the nuts 2G are backed oil toward the bight in the U-bolt vI 4 and the cable is placed in position against the seat in the keeper piece I 5. The seat member It is then placed in position and the nuts I9 threaded onto the legs of the U-bolt a suicient distance to insure ample engagement between the nuts and the bolt. The nuts I9 are threaded onto their respective legs to corresponding positions so that the wings =I3 on the seat member II) may belowered into engagement with the nuts and both nuts will operate to support the seat. The keeper piece is then lowered into contact with the cable and the nuts 20 threaded downwardly to clamp the keeper piece rmly against the cable. The nuts 20 may be provided with lock washers 2| if desired, but it will be apparent that it is not so important to lock the nuts since the weight of the cable will hold the seat piece I0 upon the nuts I 9 and retain the faces of the seat piece IIl against the faces of thenuts I9 so that it is impossible for the nuts 4I9 tobecome unscrewed from the U-bolt so as to drop the cable.

I claim:

1. A cable support comprising a cable seat, a bolt for supporting said seat, a nut for holding said seat on said bolt, said seat and nut having engaging portions for preventing rotation of said I nut, said portions being relatively movable longitudinally of said bolt out of registration with each other while said seat is assembled on said bolt and while the nut engaging portion on said seat remains at a xed distance from the axis of said bolt, said engaging portions being held in cooperative relation by gravity when said support is in operative position.

2. A conductor support comprising a seat member, a bolt for supporting said seat member, a nut threaded on said bolt, said nut engaging the lower face` of said seat member, a projection on said seat member arranged to engage the lateral face of said nut to prevent rotation of saidnut when said nut is in engagement with said lower face for supporting said seat member, said seat member being movable longitudinally of said bolt to a position in which said projection is out of registration with said nut but at the same distance from the axis of said bolt as it was while said nut was in engagement with said lower face, said lower face being held against said nut by the weight of the cable in said seat member.

3. A cable support comprising a pair of gripping members for engaging the cable, a bolt extending thro-ugh said gripping members, a pair of nuts engaging said bolt for clamping said gripping members against said cable, means for supporting said bolt in an upright position to support said cable, the lower one of said gripping members having a stop for engaging the lateral face of the lower one of said nuts to prevent said lower nut from rotation, said lower gripping member being movable on said bolt to a position in which said stop is out of engagement with said lower nut to permit rotation of said lower nut on said bolt, said stop being held in cooperative relation with said nut by the gripping action of said nuts and by the weight of said cable on the lower one of said gripping members.

4. A conductor support comprising a seat member and a keeper piece each having a pair of perforations therethrough, a pair of bolts each extending through one of the perforations in said seat member and keeper piece, a pair of nuts on each of said bolts for pressing said seat member and keeper piece together to grip the cable therebetween, means for supporting said bolts with the keeper piece above the seat member, said 7 seat member having means for cooperating with the lower one of each of said pair of nuts to lock said nuts against rotation, said seat member being movable to a position to permit rotation of the lower nuts of each pair and into operative position in which said nuts are locked against rotation, the. upper nuts being arranged to press said keeper piece and the cable held by said support downwardly upon said seat to grip said cable and to hold said seat in the position in which the l lower nuts are lockedagainst rotation.

of the seat in said seat member irrespective of which side of said keeper piece is down, said grooves being (transversely curved) upon different radii to accommodate cables of different diameters said seat member and keeper piece each having laterally extending lugs thereon provided with registering perforations, and threaded members extending through said lugs for clamping said keeper piece against the cable in the seat in said seat member.

6. A conductor support comprising a pair of clamping members for the conductor having registering openings therein, a U-bolt each arm of which extends through one pair of registering openings in said clamping members, spaced nuts on each of the arms of said U-bolt for holding said clamping members together, abutments on the outer face of the outermost clamping member for engaging the endmost nuts respectively to prevent rotation thereof, said abutment members being held in operative engagement with said nuts when the innermost nuts on said arms are in position to press said clamping members together, said innermost nuts being retractible to permit said clamping members to be moved inwardly to free said abutment members from engagement with the outermost nuts.

'7. A conductor support comprising a U-bolt, a

pair of clamping members having registering openings engaging the arms of said U-bolt respectively, spaced nuts on each of said arms for holding said clamping members upon a cable extending therebetween, means on the outermost clamping member for engaging the outermost nuts on said arms to prevent said nuts from rotation, said means being held in engagement with said nuts by the weight of the conductor on said clamping member and by the innermost nuts on said arm when said innermost nuts are in clamping position, said clamping members being movable inwardly when said innermost nuts are retracted toI free the outermost nuts from said engaging means.

8. In combination an elongated seat member having a longitudinally extending groove in the upper face thereof forming a cable seat, the ends of said cable seat being curved downwardly, a keeper piece for retaining the cable in said seat, said keeper piece having a groove therein registering with the groove in said seat member, said seat member and keeper piece each having laterally extending lugs thereon provided with registering perforations, a U-bolt having threaded legs extending through the perforations in said lugs, nuts threaded on said legs respectively for engaging the lugs on said keeper piece, and additional nuts threaded on said legs for engaging the lugs on said seat member, said nuts cooperating with said threaded legs for clamping a cable between said keeper piece and seat member, and means for locking the nuts engaging said seat member to prevent release of said cable.
